What Customers Are Saying

Customers are divided on this diagnostic tool. Many praise its affordability, ease of use, and ability to read codes, clear check engine lights, and display live engine data without requiring a smartphone—helping them avoid costly repairs. However, a substantial group reports serious frustration with software updates and registration, citing serial number validation errors, broken download links, and Windows-only support that leaves other users stranded. Some note build quality feels cheap, with USB connection issues and small display text. Despite strong capabilities, unresolved software problems have led several customers to regret their purchase.

Limited US manufacturer vehicles supported

Would Not Recommend

This code reader comes with a whole lot of supported vehicle manufacturers like - Range Rover, FIAT, Nissan, Toyota, Subaru, Suzuki and more........... BUT But it doesn't apparently support RAM, Dodge, Jeep products. Chrysler and FIAT are, but not the full line. Too Bad............ ZERO STARS

No real complaints beyond download difficulties

Would Recommend

I haven't really used this yet so I am leaving it at 4 stars for now. If it will allow me to update later I will. Hopefully to 5 stars. If it turns out this is no good, and I can't change my rating, I will just leave another. If it turns out it is good, but I can't update, then the 4 stars can stay, as there is one minor issue, and that is downloading the software to my PC from this page. I found a work around, it is RIGHT CLICK COPY LINK PASTE URL IN NEW TAB Download should start. It's ...

Love this thing! Great value for the price.

Does everything I need as a non-professional. Built fairly sturdy, buttons feel nice. Menus and interface are nicely laid out and easy to navigate. For those who are unable to update the software, not sure if this was a recent addition but there is a download link on this product page where it says "update software here". I did have to manually right click the button, copy then paste the link into my browser though to get it to download. In some browsers, it won't let you securely download the f...

Good code reader

Would Recommend

Very capable and cost effective. Every vehicle should have a stand alone OBD2 code reader, not an app or attachment to a cellphone. This is inexpensive enough that I got two - one for each car. Very easy to operate and read - buttons are clearly marked and there aren't a ton of buttons and icons to confuse the user.

I bought this product and am very excited to use is but as with some of the other reviews I Dont seem to be able to update the the software. I will come back to finish my review as soon as we get this figured out and I use the product. Right now I have no experience using the code reader but i did figure out how to change the settings to english so that is a good start.
